Tunare, Mother of All

Indestructible
As long as your devotion to green is less
than six Tunare is not a creature.
When Tunare is cast, search your library
for up to two Forests, and one Elf creature
and put them on the battlefield.
At the beginning of combat Tunare and Elves you control get +X/+X for each Forest you control, divided in half, until the end of the turn.
